摘要
863课题“近景目标三维测量技术”中,扫描仪极坐标系统如何向当地坐标系统转换是系统急需解决的关键问题之一。课题中涉及到多个坐标系统,本文提出一种多坐标系统转换方法,通过建立起多个坐标系统之间的转换关系,最终实现扫描仪坐标系统向当地坐标系统转换。实验结果表明,转换方法可靠,可满足系统精度要求。
The conversion of LS coordinate system to local coordinate system is one of key problems in 863 Project 'close range 3D measurement technology'. The Project involves multi-coordinate system. The paper presents a method of multi-coordinate system conversion and completes conversion of LS coordinate system to local coordinate system through establishment relations of multi-coordinate conversion. The results of tests indicate that the method is reliable and it can meet precision request of system.
